JesusAAP,
I think you may be trying to activate too much at one time.
Remember, the key to the PRing is multiple passes. Don't spend too much time on one activation. The first pass sometimes feel like you've just "skimmed" it, especially when it's just superreading and dipping. It's the third or more pass (for the beginners) that "gels" the book.
Try to keep this estimate: a book that would take you 10 hours should take you around 3 hours. Don't forget to all the steps if you haven't gotten it to work yet. This includes mindmapping, mindprobing, affirmations, the whole works. Don't skip steps until you've gotten the system to work for you for awhile.
Hope that helps.
